Hi Bert,

Is there any progress in determine which capacitors sound best in your BD30? I understood BG is no longer available...
Did you also make up your mind for providing it to the DIY's? I really would want to know...:grin:

maybe Panasonic FC ?
a good contender in tube catodes and filament supplies anyway

Hi Leif,

Nope, the FR series (much lower impedance which is good if you are looking for good bass!). Perhaps for the CrazyA amps the FC would be preferable though...

Yes and testing with Panasonic FR capacitors working out very well... :cool:

Yes, these are for DIY and not that much worse than the BG's. A bit less "square" being more rounded in the bass but very well controlled.

Still wiping the floor with all those Class D and switching amps by much! :clapping:

OK
FC is good in cathode and filaments though
BD-30 is a terrific amp!
should have bought more than 4 while I had the chance!maybe one for each BD15?:grin:
any point in that?what´s the value of those BG N in the BD-30 again?
I have quite a few lying around in my "workshop":cool:

Hi Leif,

BD-30 is a terrific amp!

Yes, I know and that is why I am still using them... :yeah:

should have bought more than 4 while I had the chance!maybe one for each BD15? :grin:
any point in that?

It will be absolutely useless to add extra amps. Adding more BD15's would do a lot more... :bass:

what´s the value of those BG N in the BD-30 again?

680uF/35V Nx

I have quite a few lying around in my "workshop":cool:

You'll need 12 for each amplifier...

are they 680µF/35vdc Nx?
will 1000µF/25vdc do? or is the voltage too low?

No, you'll need 35V Voltage minimum.

Yep, those are the ones used and getting more expensive than they already were!

Perhaps I should sell the last series I have here in pairs and not use them for the BD30's anymore... ;-)

That's all which is different, the smaller BG's on the printed board are widely more available so this can remain the same for a while... :cool:

Hi Bert,

Thanks, that's good news! :grin: Will it be a complete kit or a ready built board for DIY? And do you have any idea about the price and delivering options?

It will be something similar as previously done with the BD30's. The amp board will be fully completed and assembled on an Aluminum plate with transformer, the only thing left for you to do will be connecting the input, output and the mains to it to have it fully operational.

Price will be 389 Euro for the pair (VAT and also crossovers, plugs, binding posts and such not included).

Bert, I see BD30 amplifiers referenced a lot but can't find anything about them on the website?

I have the impression that they are a gainclone variant but might be wrong? Where can I find out more about them?

Hello Ray,

I have the impression that they are a gainclone variant but might be wrong? Where can I find out more about them?

It is a gainclone variant yes but it can't be found on the website anymore. It was discontinued due to the limited available Black gate capacitors for the power supply. The original BD30 is only available for completed systems but that will end pretty soon too as I am almost out of stock now.

The new BD30mkII will replace them though...

Cheers,

Bert

PS The website needs a major update but I am still figuring out myself which path I want to follow as main business but until then many things are (still) possible except giving away secrets of course...

The Forum is the place to ask and to follow for most actual information.

Thanks Bert. I hope I didn't give the impression that I want to know you're secrets - I'm new here and there seem to be lots of things that others know about but which I caNot easily find out about. Please bear with me.

No worries Ray, I was only thinking out loud trying to give some general information. It's no secret the BD30 is a gainclone variant... :wink:

I hope I will have saved the money in time to buy the BD30's and a pair of BD15's :blush:
